OK, about a month ago i was driving my E-Maxx at a local park, and I twisted both of my rear drive shafts. I bought all of the parts needed to fix it. But my question is what is the best way to get the old drive shafts off the little metal U-Joints. I have tried hard and I've put it up for now. Is there any tips or tricks you guys can tell me about before I try again? I'm away at my grandmothers house 3 hours away so I would really like to be able to drive my truck while I'm gone, oh and there isn't a Hobby Shop within a good ways away too.
